Elbow support



FIG. 1 is a front elevational view of an elbow support showing our new design;

FIG. 2 is a right side elevational view thereof;

FIG. 3 is a left side elevational view thereof; and,

FIG. 4 is a back elevational view thereof.

The surface treatments consisting of the light and heavy stippling and broken hatched lines are understood to extend uniformly across the indicated structures to which they are applied.

The ornamental design that is claimed is shown in solid lines in the drawings. The broken lines showing an arm portion illustrate environmental structure and form no part of the claimed design. 

We claim the ornamental design for an elbow support, as shown and described.
